Stylesheet Font properties are UIColor, not UIFont about issue_tracking

Sorry @mattmalinoski - tested pretty thoroughly on native, but not so much Xamarin...

Just tested with the following:

            var styles = STASDKUIStylesheet.SharedInstance;
            styles.HeadingTextColor = UIColor.Red;
            styles.SubheadingTextColor = UIColor.Blue;
            styles.BodyTextColor = UIColor.Yellow;

            styles.HeadingFont = UIFont.SystemFontOfSize(24, 100);
            styles.SubHeadingFont = UIFont.SystemFontOfSize(18, 50);
            styles.BodyFont = UIFont.SystemFontOfSize(10, 5);
            styles.NavigationBarFont = UIFont.SystemFontOfSize(10, 1);

Should be fixed now on rc3.
